Girault Pastels are made of natural pigments that are traditionally used in fine arts.
Colors are created through the blending of pure pigments; pastels are made by mixing these pigments with white.
Special attention is paid to keep the hardness of the sticks the same throughout the whole series.
First,
the pigments and the white are ground; then water is added and the
paste is mechanically wrung and molded into the required shape before
being manually cut at the needed length.
The sticks are numbered and stamped and then left to dry.
